บทคัดย่อ

The major problems for exporting longan are pericarp browning, fungal infection and insect infestation. Sulfur dioxide (SO2) fumigation has been reported to control diseases and prevent browning, while gamma irradiation has been used to control insect infestation in longan fruit. Because of the high cost of fuel, sea transportation is an alternative for exporting commodities, but takes more time to reach the destinations. Therefore, the objective of this research was to study the responses of irradiated 'Daw' longan to simulated shipment by sea. Fruits were fumigated with SO2 at the commercial concentration at the packinghouse in Chiangmai province and then transported to Bangkok within 24h. The fruit were packed in cardboard boxes with polyethylene bag (PE) liner and 2 or 3 sheets of the dual release sulfur dioxide (DRSD) pads and then stored at 2ฐC for 30 days. Fruit packed in cardboard boxes without plastic bags and DRSD pad served as the control. Sulfur residues in pericarp tissue gradually reduced as storage time increased, while no residues were detected in pulp. DRSD pads significantly reduced disease incidence. Pericarp browning, indicated by L values, was reduced in fruit that were stored in PE bag with 3 DRSD pads. PE bags significantly reduced the weight loss and maintained soluble solids content.
